AUERBACH, or SALT LAKE CITY, UTAH CAP LOCK Application filed January 7, 1931.

The invention relates to a device for locking caps upon the filling necks of tanks, the primary use being for securing the caps of automobile gas tanks in place to prevent loss and to prevent thefi; of fuel.

It is the object of the invention to provide an exceptionally simple and inexpensive device of the class set forth, yet one which will be efiicient and long-lived, and may be easily applied and released. 7

With the foregoing in View, the invention resides in the novel subject matter hereinafter described and claimed, description being accomplished by reference to the accompanying drawings.

Fig. 1 is a side elevation.

Fig. 2 is a horizontal sectional view substantially on line 2-2 of Fig. 1.

Fig. 3 is a perspective view.

The preferred construction has been illustrated and will be specifically described, with the understanding however that within the scope of the invention as claimed, variations may be made.

The numeral 4 denotes a metal collar to snugly surround the filling neck N of a tank T. At one point, this collar is radially split as denoted at 5, said collar being provided at opposite sides of said split, with relatively short and long lugs 6' and 7 respectively, lug 7 being provided with an opening 8 beyond the outer end of the lug 6. The two lugs 6 and 7 are intended to be rigidly secured together, for instance by a rivet 9, after the collar is placed around the neck N and the rivet or other securing means is such that said collar is held fixedly upon the neck.

At a point diametrically opposed to the split 5, the collar 4 is provided with a third rigidly attached lug 10 having a vertical opening 11, said lug 10 and the lugs 6 and 7 being all by preference integral with the collar. The opening 11 rotatably receives one vertical leg 12 of a one-piece arched yoke 13, the other leg 14 of said yoke having a flattened terminal 15 adapted to lie against a vertical side of the lug 7 when the yoke is horizontally swung to the position of Fig. 1. The yoke terminal 15 is provided with an opening 16 to aline with the opening 8, allowing passage of Serial No. 507,246.

the shackle 17 of a lock 18, through said openings. The yoke 13 is thus held in place over the conventional cap C on the neck N, so that this cap cannot be removed by unauthorized persons.

While any appropriate provision may be made for holding the leg 12 against vertical sliding through the opening 11, said leg is preferably provided with screw threads 19 engaging corresponding threads in the side wall of the opening.

It will be seen from the foregoing that novel provision has been made for carrying out the objects of the invention, and attention is again invited to the fact that within the scope of said invention as claimed, variations may be made.

I claim 1. A look for the cap of a tank filling neck, comprising a neck-encircling collar transversely split at one point and having out-' wardly projecting relatively long and short lugs at opposite sides of the split, said collar having a third outwardly projecting lug substantially diametrically opposite said split, means for securing said relatively long and short lugs together to rigidly secure the collar around the. neck, the relatively long lug being formed with a horizontal opening disposed beyond the relatively short lug, said third lug having a vertical opening, and an arched one-piece yoke having one of its legs rotatably mounted in said vertical opening, the other leg of said yoke being adapted to swing against one vertical side of said relatively long lug and having an opening for registration with the opening of the latter, said openings being adapted to receive a lock shackle.

2. A look for the cap of a tank-filling neck, 90 comprising a collar adapted to fixedly surround the neck, said collar being provided with outwardly projecting lugs at diametrically opposed points, one of said lugs being provided with a vertical opening and the 95 other with a horizontal opening, a horizontal crown bar to overlie the tank cap, a downwardly projecting leg integral with one end of said crown bar and having its lower end rotatably and nonslidably received in said i vertical opening, and a second downwardly projecting leg integral with the other end of 7
